Hi, It most likely is a faulty power supply or a motherboard issue. Remove the power cord then press and hold the power button for at least 30 seconds. Then plug it back in and hit the power button. This will release any static buildup that might be in the computer and sometimes that causes it not to boot. If nothing is happening it is more likely your power supply than the motherboard.

Take out all peripherals connected to computer including AC adapter.
Take out battery.
Press and hold power button for several seconds with all power sources removed. This drains residual power from the system and may correct many problems.
Connect the AC adapter to wall, then computer. Press the power button to start the notebook PC.

If the link doesn't help it is at HP website, Troubleshooting, I looked at Compaq Presario v3000 series, and went to boot-up problems...it was pretty far down the page under the heading Other Problems. There is more info if the first part (above) that you do does not work. Hope this is helpful to others!
